# Design QA

- Source visual truth: `/workspace/scratch/6e52996114b8/upload/18c36dd0-af66-494f-9633-c0f6466a7cc9.png`
- Source pixel dimensions: `2048 × 106`.
- Intended implementation viewport: PC dark theme, approximately `2048px` CSS width.
- Implementation screenshot: unavailable.
- CSS size and density normalization: unavailable because the implementation could not be opened in the cloud browser.
- State: 形态图片页顶部工具栏，主图统计在左、图库操作在右。

## Full-view comparison evidence

The source crop was opened and inspected. The toolbar content sits inside a tall horizontal band, while the summary and actions are separated by nearly the full desktop width. This makes the content appear vertically loose and the center read as a large unused region.

The component now uses symmetric `5px` vertical padding and a shared `34px` minimum alignment height for the toolbar, summary, and actions. On PC widths the actions no longer use automatic left margin, so the controls follow the summary as one compact toolbar group. Mobile keeps the existing split alignment.

A local Sites preview started successfully, but the cloud browser rejected `terminal.local` with `net::ERR_BLOCKED_BY_CLIENT`. Therefore no browser-rendered implementation screenshot is available.

## Focused region comparison evidence

- Vertical alignment: summary and action groups share a `34px` alignment box with centered items.
- Header density: top and bottom padding are both `5px`.
- PC horizontal rhythm: automatic spacer is removed only above `760px`, preventing the wide empty center.
- Mobile behavior: the existing `margin-left: auto` remains active at `760px` and below.

These are code-level checks only and do not replace a rendered focused-region comparison.

## Required fidelity surfaces

- Fonts and typography: unchanged; browser comparison is blocked.
- Spacing and layout rhythm: header padding is symmetric and the PC toolbar is grouped continuously.
- Colors and visual tokens: unchanged.
- Image quality and asset fidelity: no image behavior changed.
- Copy and content: unchanged.

## Findings

- [P1] Browser-rendered comparison unavailable
    - Location: 形态图片页顶部工具栏。
    - Evidence: the required cloud browser returns `net::ERR_BLOCKED_BY_CLIENT` for the healthy local preview.
    - Impact: exact vertical centering, final toolbar width, responsive transition, and console state cannot be visually certified.
    - Fix: capture the page in an available browser at the same desktop width and compare the toolbar crop.

## Primary interactions tested

Automated style-contract tests protect the symmetric padding, shared alignment height, and PC-only removal of the automatic spacer. All 275 tests pass. Browser interactions were unavailable.

## Console errors checked

Not checked because the page could not be opened in the cloud browser.

## Comparison history

- Iteration 1: identified asymmetric perceived vertical spacing and an oversized empty center caused by right-pushing the action group.
- Iteration 2: normalized the toolbar to a compact `44px` total height and grouped desktop actions beside the summary. Full tests and production build pass; browser capture remains blocked.

## Implementation checklist

- [x] Center summary and actions within the same toolbar height.
- [x] Use equal top and bottom header padding.
- [x] Remove the wide PC-only automatic spacer.
- [x] Preserve the existing mobile split layout.
- [x] Add style-contract regression assertions.
- [ ] Capture and compare the rendered desktop state in the cloud browser.

final result: blocked
